Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] The present application claims priority to and incorporates
by reference the entire contents of Japanese Patent Application No.
2016-165014 filed in Japan on Aug. 25, 2016.
FIELD
[0002] A disclosed embodiment relates to a sanitary washing device
and a toilet apparatus.
BACKGROUND
[0003] A sanitary washing device has conventionally been known that
is installed on an upper surface of a toilet, and executes washing
of, for example, a private part of a person that sits on a toilet
seat. In such a sanitary washing device, a water supply pipe may be
installed so as not to be exposed to an outside thereof, for
example, so as to hide the water supply pipe in an internal space
of a toilet (see, for example, Japanese Laid-open Patent
Publication No. 2014-189999). Accordingly, a through-hole where a
water supply pipe is inserted therethrough is provided on an upper
surface of a toilet in order to introduce the water supply pipe
into an internal space of the toilet (see, for example, Japanese
Laid-open Patent Publication No. 2014-147445).
[0004] However, in a conventional sanitary washing device as
described above, for example, a through-hole of a toilet may be
provided at a variety of positions depending on a specification
thereof, so that a water supply pipe that does not correspond to a
position of a through-hole may be exposed to an outside thereof to
degrade a design or appearance thereof or complicate construction
thereof. That is, there is room for improvement in a conventional
sanitary washing device in that a design or construction thereof is
improved.
SUMMARY
[0005] It is an object of the present invention to at least
partially solve the problems in the conventional technology.
[0006] According to an aspect of an embodiment, a sanitary washing
device includes a casing, a water supply pipe that is connected to
the casing, and a recess that is arranged on one of left and right
peripheral sides of the casing and forms, on a lower surface of the
casing, an open space capable of laying the water supply pipe.

DESCRIPTION OF EMBODIMENT
[0024] Hereinafter, an embodiment of a sanitary washing device and
a toilet apparatus as disclosed in the present application will be
described in detail, with reference to the accompanying drawings.
Herein, this invention is not limited by an embodiment as
illustrated below.
[0025] Toilet Apparatus
[0026] First, a general configuration of a toilet apparatus 1
according to an embodiment will be described with reference to FIG.
1 and FIG. 2. FIG. 1 and FIG. 2 are schematic perspective views of
a toilet apparatus 1 according to an embodiment. Among these, FIG.
2 illustrates a mounting state of a sanitary washing device 10.
[0027] Herein, FIG. 1 and FIG. 2 illustrate a three-dimensional
orthogonal coordinate system that includes a Z-axis with a positive
direction being a vertically upward direction in order to cause the
description to be readily understood. Such an orthogonal coordinate
system may be illustrated in another drawing.
[0028] Furthermore, such an orthogonal coordinate system defines a
view in a positive direction of a Y-axis as a front view and also
defines a view in a positive direction of an X-axis, a view in a
negative direction of the X-axis, and a view in a negative
direction of the Z-axis, as a left side view, a right side view,
and a plan view (that may also be referred to as a "top view"),
respectively. Accordingly, in the following description, directions
of the X-axis, directions of the Y-axis, and directions of the
Z-axis may be referred to as leftward and rightward directions,
forward and backward directions, and upward and downward
directions, respectively.
[0029] As illustrated in FIG. 1, a toilet apparatus 1 includes a
toilet bowl part 2, a toilet lid part 3, and a sanitary washing
device 10. Herein, the toilet bowl part 2 is not limited to a
floor-mounted type but may be a wall-hung type. Furthermore,
although a washing water tank (illustration omitted) that stores
washing water is installed in back of the toilet bowl part 2 in an
illustrated example, the toilet apparatus 1 may be a so-called
tank-less type where a washing water tank is not installed in back
of the toilet bowl part 2.
[0030] Furthermore, the toilet bowl part 2 has a bowl 2b (see FIG.
2) that is provided on an upper surface of a toilet body (that will
be referred to as a "toilet" below) 2a and receives sewage. Herein,
the toilet bowl part 2 further has a headrace that introduces
washing water to the bowl 2b, a trap pipeline that has an inlet
connected to a bottom of the bowl 2b and discharges sewage in the
bowl 2b to a drainage pipeline, and the like. Herein, the toilet 2a
is made of, for example, a ceramic.
[0031] Furthermore, the toilet apparatus 1 is, for example, a
so-called siphon type where sewage in the bowl 2b is suctioned into
and discharged through a trap pipeline by utilizing siphonage.
Herein, the toilet apparatus 1 is not limited to a siphon type but
may be, for example, a so-called wash-out type where sewage is
washed out by action of running water that is caused by a head drop
of washing water in the bowl 2b.
[0032] Furthermore, the toilet 2a has an internal space.
[0033] For example, a cover 2c is mounted on a rear half part of
the toilet 2a, so that an internal space of the toilet 2a is formed
between the toilet 2a and the cover 2c. A connection component 13
(see FIG. 2) of the sanitary washing device 10 is housed in an
internal space of the toilet 2a.
[0034] The toilet lid part 3 is mounted on top of the toilet 2a.
The toilet lid part 3 includes a toilet lid 3a and a toilet seat
(illustration omitted). A rear edge of the toilet lid part 3 that
is a rotation edge of the toilet lid 3a or the toilet seat in an
upward or downward direction is mounted on the sanitary washing
device 10. Furthermore, the sanitary washing device 10 is installed
on an upper surface of the toilet 2a. That is, the sanitary washing
device 10 is provided between the toilet bowl part 2 and the toilet
lid part 3.
[0035] As illustrated in FIG. 2, the sanitary washing device 10 is
installed on a rear part of an upper surface of the toilet 2a and
sprays washing water toward, for example, a private part of a
person that sits on a toilet seat to wash the private part of a
person that sits on a toilet seat. In the sanitary washing device
10, the connection component 13 of a functional part (illustration
omitted) provided inside a casing 11 (see FIG. 3) is provided to be
directed from an inside of the casing 11 to an outside thereof.
That is, the connection component 13 is exposed to an outside of
the casing 11.
[0036] The connection component 13 may be, for example, a water
supply pipe 13a that is connected to a water supply source
(illustration omitted) or an electrical power supply cord 13b that
is connected to an electrical power supply (illustration omitted).
Furthermore, the connection component 13 may be a toilet washing
jack 13d (see FIG. 4B) with a toilet washing plug 13c (see FIG. 4A)
being connected thereto.
[0037] That is, the connection component 13 includes the water
supply pipe 13a, the electrical power supply cord 13b, and the
toilet washing lack 13d. Herein, the connection component 13 may
include the toilet washing plug 13c. In such a case, the toilet
washing plug 13c includes a cord portion that extends from a plug
portion.
[0038] Herein, for example, in a case where a rotation lever that
is provided on an outer side of a washing water tank and operated
at a time of washing of the toilet 2a is operated by remote
control, the toilet washing plug 13c electrically connects the
sanitary washing device 10 and motor that drives the rotation lever
to provide an electrical power supply via the sanitary washing
device 10.
[0039] Furthermore, the sanitary washing device 10 is installed on
the toilet 2a while water supply and electrical power supply is
hidden in such a manner that the connection component 13 does not
come into a field of view of a user in a case of installation
thereof, that is, the connection component 13 is not exposed to an
outside of the toilet apparatus 1.
[0040] In a case where the sanitary washing device 10 is installed
on a rear part of an upper surface of the toilet 2a, the connection
component 13 is inserted through a through-hole 2d provided on one
of left and right sides (a left side in an illustrated example) on
a rear part of an upper surface of the toilet 2a and housed in an
internal space of the toilet 2a via the through-hole 2d. For
example, the connection component 13 housed in an internal space of
the toilet 2a penetrates through a wall 5 of a toilet room and is
connected to a water supply source or an electrical power supply
provided in a wall 5 without being exposes to an outside of the
toilet apparatus 1.
[0041] Accordingly, the sanitary washing device 10 is configured to
be capable of being preferably installed while water supply and
electrical power supply is hidden. Additionally, a detail of the
sanitary washing device 10 will be described later by using FIG. 3
and subsequent figures. Furthermore, as illustrated in FIG. 2, the
sanitary washing device 10 is mounted on the toilet 2a via a
mounting plate 4.
[0042] The mounting plate 4 is provided on a central part on a rear
part of an upper surface of the toilet 2a and fixes the casing 11
between an upper surface of the toilet 2a and the casing 11 (a case
plate 11b). The casing 11 is slid on an upper surface of the
mounting plate 4 in a forward or backward direction, so that the
casing 11 is attached thereto or detached therefrom.
[0043] As the casing 11 is sild from a front side to a back side by
a predetermined amount, the casing 11 is mounted on the mounting
plate 4. Furthermore, as the casing 11 is slid from a back side to
a front side by a predetermined amount, the casing 11 is detached
from the mounting plate 4. Thus, the mounting plate 4 fixes the
sanitary washing device 10 and couples the toilet bowl part 2 and
the toilet lid part 3 via the sanitary washing device 10.
[0044] Sanitary Washing Device
[0045] Next, a configuration of the sanitary washing device 10
according to an embodiment will be described with reference to FIG.
3 to FIG. 5. FIG. 3 is a schematic perspective view of the sanitary
washing device 10 according to an embodiment. FIG. 4A and FIG. 4B
are schematic side views of the sanitary washing device 10
according to an embodiment. FIG. 5 is a schematic bottom view of
the casing 11.
[0046] Herein, FIG. 4A and FIG. 4B illustrate a left side surface
of the sanitary washing device 10. Furthermore, FIG. 4A illustrates
a state where a case cover 11a is mounted thereon, and FIG. 4B
illustrates a state where the case cover 11a is detached
therefrom.
[0047] As illustrated in FIG. 3, the sanitary washing device 10
includes the casing 11, a functional part (illustration omitted),
and for example, the water supply pipe 13a that is the connection
component 13 (see FIG. 2) in the functional part. The casing 11
includes a case cover 11a that is a top part of the casing 11 and a
case plate 11b that is a bottom pat of the casing 11. The
functional part is housed in the casing 11. Specifically, the
functional part is mounted on the case plate 11b and an upper side
thereof is covered by the case cover 11a.
[0048] The functional part has, for example, a sanitary washing
nozzle that washes a private part of a person that sits on a toilet
seat, a deodorization device that eliminates an odor in the bowl 2b
(see FIG. 2), or the like, as well as devices that contribute to
water supply and electrical power supply functions. Herein, the
functional part is arranged on one surface of the case plate 11b.
Furthermore, the functional part has the connection component 13
for external connection (see FIG. 2).
[0049] As described above, the connection component 13 includes the
water supply pipe 13a, the electrical power supply cord 13b, the
toilet washing plug 13c, and the toilet washing jack 13d.
[0050] Herein, the through-hole 2d (see FIG. 2) of the toilet 2a is
provided on, for example, a left side on a rear part of an upper
surface of the toilet 2a. Accordingly, in the sanitary washing
device 10, the connection component 13 as described above, namely,
the water supply pipe 13a, the electrical power supply cord 13b,
the toilet washing plug 13c, and the toilet washing jack 13d, may
be arranged so as to be concentrated in a left side on a rear part
of the casing 11 (case plate 11b).
[0051] Thereby, in a case where installation is executed while
water supply and electrical power supply is hidden, work for hiding
the water supply pipe 13a or the electrical power supply cord 13b
is facilitated, and thereby, it is possible to improve construction
thereof. Furthermore, the water supply pipe 13a or the electrical
power supply cord 13b is not exposed to an outside thereof, and
hence, an appearance is improved in a design. Thereby, it is
possible to improve a design.
[0052] The casing 11 is mounted on an upper surface of the toilet
2a (see FIG. 2). A decorative cover 14 is mounted on the casing 11
at a site where the water supply pipe 13a or the electrical power
supply cord 13b is arranged, that is, at a rear edge and a left
edge of the casing 11 in such a manner that the water supply pipe
13a or the like is not exposed to an outside thereof. The
decorative cover 14 covers at least a side surface of the casing
11. Herein, a part that is covered by the decorative cover 14 is
provided with a notch or a hole so as to separate an inside and an
outside of the casing 11 and be accessible to the toilet washing
jack 13d or the like.
[0053] Thus, a part that is exposed to an outside of the casing 11
is hidden by the decorative cover 14, so that it is possible to
further improve a design thereof. Furthermore, in such a case, when
a color of the decorative cover 14 is identical to, for example, a
color of the casing 11, the toilet bowl part 2 (toilet 2a), or the
like, it is possible to readily improve a design thereof. Herein,
the decorative cover 14 is made of, for example, a resin.
[0054] Furthermore, a part of the decorative cover 14 that is
arranged on at least a side surface of the casing 11 extends
downward.
[0055] Furthermore, the casing 11 is provided with a recess 12 at a
site where the water supply pipe 13a or the electrical power supply
cord 13b is arranged, that is, at a rear edge and a left edge of a
lower surface (that is also referred to as a "bottom surface") of
the casing 11. In other words, the recess 12 is arranged on one of
left and right peripheral sides of the casing 11. The recess 12 is
a site that is formed into a spot-facing shape so as to have a step
against another site on a lower surface of the casing 11.
[0056] The recess 12 forms an open space 20 where, for example, an
end edge of a side surface (for example, a left side surface) to a
start end of a back surface of the casing 11 is opened, in a state
where the casing 11 is mounted on the toilet 2a. That is, the open
space 20 is formed by an upper surface of the toilet 2a, a lower
surface of the casing 11 (recess 12), and a side wall surface of
the recess 12. The recess 12 and the open space 20 will be
described later by using FIG. 4A, FIG. 4B, and FIG. 5.
[0057] As illustrated in FIG. 4A and FIG. 4B, in the sanitary
washing device 10, in a case where the water supply pipe 13a, the
electrical power supply cord 13b, the toilet washing plug 13c, and
the toilet washing jack 13d are arranged in the recess 12 (open
space 20 in a case where the casing 11 is installed on the toilet
2a) provided on a lower surface of the casing 11 (that is also
referred to as a case plate 11b). Herein, the decorative cover 14
is mounted on the casing 11, so that it is not possible to view an
inside of the recess 12 from an outside thereof.
[0058] Furthermore, one end of the water supply pipe 13a is
connected to a water supply inlet (illustration omitted) on a lower
surface of the casing 11, in other words, on a surface that is
opposite to an upper surface of the toilet 2a in a case where the
casing 11 is installed on the toilet 2a (see FIG. 2). Furthermore,
the other end of the water supply pipe 13a is connected to a water
supply source. Furthermore, the water supply pipe 13a is rotatably
connected to a lower surface of the casing 11 in a direction of the
lower surface.
[0059] As illustrated in FIG. 5, the recess 12 is provided on a
lower surface of the casing 11. Furthermore, as described above,
the water supply pipe 13a is arranged in the recess 12 to form the
open space 20 in a state where the casing 11 is mounted on the
toilet 2a. In the open space 20, the water supply pipe 13a, the
electrical power supply cord 13b, or the like is arranged to be
capable of being laid. Furthermore, the through-hole 2d (see FIG.
2) provided on an upper surface of the toilet 2a is arranged in the
open space 20.
[0060] Thus, it is possible to arbitrarily arrange the water supply
pipe 13a in the open space 20 in the sanitary washing device 10
according to an embodiment, and hence, it is possible to draw the
water supply pipe 13a in an arbitrary direction in the open space
20. Thereby, it is possible to lay the water supply pipe 13a in an
arbitrary direction in the open space 20, and further, it is
possible to lay the water supply pipe 13a on a back surface of the
casing 11 without being exposed to a side surface of the casing 11,
so that it is possible to improve a design.
[0061] Furthermore, the water supply pipe 13a is rotated in the
open space 20, so that it is possible to lay he water supply pipe
13a is rotated in the open space 20. Furthermore, it is possible to
correspond to the through-hole 2d that is provided at an arbitrary
position of the toilet 2a. Thereby, it is possible to insert the
water supply pipe 13a through the through-hole 2d readily and
reliably. Thereby, an installation operation on the toilet 2a is
facilitated, so that it is possible to improve a design thereof.
Furthermore, it is also possible to lay the water supply pipe 13a
outside the casing 11, and hence, even in a case where the
through-hole 2d is absent in the toilet 2a, an installation
operation is facilitated, so that it is possible to improve a
design.
[0062] Furthermore, the electrical power supply cord 13b is
arranged in the recess 12 as described above. That is, the
electrical power supply cord 13b is arranged in the open space 20
in a state where the casing 11 is installed on the toilet 2a (see
FIG. 2).
[0063] Thus, the electrical power supply cord 13b is arranged in
the open space 20 in the sanitary washing device 10 according to an
embodiment, and hence, it is possible to arbitrarily lay the
electrical power supply cord 13b in the open space 20, so that it
is also possible to improve a design of the electrical power supply
cord 13b. Furthermore, it is possible to insert the electrical
power supply cord 13b through the through-hole 2d. Thereby, it is
possible to hide the electrical power supply cord 13b. Furthermore,
the electrical power supply cord 13b is not exposed to an outside,
so that it is possible to improve a design.
[0064] Furthermore, the open space 20 has an opened part (that will
be referred to as an "open part" below) from a side surface to a
back surface of the casing 11. An open part of the open space 20 is
covered by the decorative cover 14 that extends downward.
[0065] Thus, it is possible for the decorative cover 14 to hide an
inside of the open space 20 from an outside thereof in the sanitary
washing device 10 according to an embodiment. Thereby, it is
possible to hide the water supply pipe 13a, the electrical power
supply cord 13b, or the like that is arranged in the open space 20.
Furthermore, the water supply pipe 13a, the electrical power supply
cord 13b, or the like is not exposed to an outside, so that it is
possible to improve a design.
[0066] As illustrated in FIG. 5, the water supply pipe 13a is
rotated in a direction of a lower surface of the casing 11 while
one end that is connected to a water supply inlet is a supporting
point of rotation. The casing 11 includes, in the recess 12, a
rotation restriction part 21 that contacts the water supply pipe
13a and restricts frontward rotation of the water supply pipe 13a.
Herein, it is preferable for the rotation restriction part 21 to
restrict rotation of the water supply pipe 13a at a position where
the water supply pipe 13a is housed in the recess 12.
[0067] Herein, in an example as illustrated in FIG. 5, the rotation
restriction part 21 restricts rotation of the water supply pipe 13a
so as to provide a predetermined angle of rotation .alpha..
Furthermore, the water supply pipe 13a is held at a predetermined
position by the rotation restriction part 21 so as to be housed in
the recess 12.
[0068] Thus, in the sanitary washing device 10 according to an
embodiment, for example, an installation operation is executed in a
state where rotation of the water supply pipe 13a is restricted by
the rotation restriction part 21, so that it is possible to prevent
rotation of the water supply pipe 13a to disturb an installation
operation and the installation operation is facilitated. Thereby,
it is possible to improve a design. Furthermore, effectiveness is
also provided in a case where an installation operation is executed
in a state where it is not possible to view a mounting
position.
[0069] Herein, the water supply pipe 13a (and a water supply pipe
130a) will be described with reference to FIG. 6A and FIG. 6B. FIG.
6A is a schematic cross-sectional side view of the water supply
pipe 13a. FIG. 6B is a schematic cross-sectional side view of
another example of a water supply pipe (water supply pipe 130a). As
illustrated in FIG. 6A, the water supply pipe 13a includes a water
supply inlet side edge 131 that is connected to a water supply
inlet and causes washing water to flow into an inside of the casing
11 (see FIG. 5), a water supply source side edge 132 that is
connected to a water supply pipe (flexible hose) that extends from
a water supply source, a first coupling part 133 that extends in a
horizontal direction, and a second coupling part 134 that extends
in a vertical direction.
[0070] That is, the water supply pipe 13a is formed into a crank
shape and has two substantially rectangular curved parts. In the
water supply pipe 13a, washing water that is supplied from the
water supply source side edge 132 flows through a flow channel 135b
of the second coupling part 134 in a vertical direction,
subsequently flows through a flow channel 135a of the first
coupling part 133 in a horizontal direction, and flows through a
flow channel of the water supply inlet side edge 131, and the
washing water is supplied to a water supply inlet. Herein, the
water supply pipe 13a is made of, for example, a metal.
[0071] Furthermore, as illustrated in FIG. 6B, the water supply
pipe 130a of a so-called elbow type that has one substantially
rectangular curved part may be used instead of the water supply
pipe 13a. That is, it is sufficient for a water supply pipe that is
used for the sanitary washing device 10 to have at least one curved
part. The water supply pipe 130a is different from the water supply
pipe 13a of a crank type that is dropped in the through-hole 2d and
drawn from an open part of the open space 20 to a side of the
casing 11. Herein, the water supply pipe 130a includes a water
supply inlet side edge 136 that is connected to a water supply
inlet and causes washing water to flow into an inside of the casing
11 (see FIG. 5), a water supply source side edge 137 that is
connected to a water supply pipe (flexible hose) that extends from
a water supply source, and a coupling part 138 that extends in a
horizontal direction.
[0072] Furthermore, the toilet bowl part 2 will be described
herein, with reference to FIG. 7. FIG. 7 is a schematic plan view
of the toilet bowl part 2. As described above, the toilet bowl part
2 includes the toilet 2a, the bowl 2b, the cover 2c (see FIG. 2),
and the through-hole 2d. The toilet bowl part 2 further includes an
installation table 2e where a washing water tank (illustration
omitted) is installed. Furthermore, the mounting plate 4 is mounted
on a central part of a rear part of the toilet 2a.
[0073] Furthermore, as illustrated in FIG. 7, the through-hole 2d
where the water supply pipe 13a or the electrical power supply cord
13b (see FIG. 5) is inserted is provided on a left side with
respect to a center line 0 of the toilet 2a, preferably, provided
on a left side of the mounting plate 4. The water supply pipe 13a
or the electrical power supply cord 13b is inserted through the
through-hole 2d in a state where the casing 11 is installed on an
upper surface of the toilet 2a. In addition, the toilet washing
plug 13c (see FIG. 4B), or for more detail, a cord that extends
from the toilet washing plug 13c is inserted through the
through-hole 2d.
[0074] Next, routing of the water supply pipe 13a and the
electrical power supply cord 13b in a state where the casing 11 is
mounted will be described with reference to FIG. 8. FIG. 8 is an
illustration diagram of routing of the water supply pipe 13a and
the electrical power supply cord 13b. Herein, FIG. 8 schematically
illustrates, in a plan view, the open space 20 in a state where the
casing 11 (see FIG. 5) is mounted.
[0075] As illustrated in FIG. 8, the through-hole 2d is arranged in
the open space 20 formed by the recess 12 of the casing 11 and an
upper surface of the toilet 2a. Furthermore, the water supply pipe
13a and the electrical power supply cord 13b are inserted through
the through-hole 2d in the open space 20. In such a case, even when
the through-hole 2d is provided at an arbitrary position, the water
supply pipe 13a is rotated, so that it is possible to insert the
water supply pipe 13a through the through-hole 2d.
[0076] Furthermore, a length L of the open space 20, that is, the
recess 12 on a lower surface of the casing 11, in forward and
backward directions (directions of the Y-axis) is provided to be a
length equivalent to an amount of sliding in forward and backward
directions in a case where the casing 11 is mounted on the mounting
plate 4 (see FIG. 7).
[0077] Thus, in the sanitary washing device 10 according to an
embodiment, a length of the recess 12 of the casing 11 in forward
and backward directions is a length equivalent to an amount of
sliding for mounting the casing 11, so that it is possible to
reliably arrange the recess 12, for example, at a position that
includes the through-hole 2d in the open space 20, due to sliding
of the casing 11. That is, it is possible to realize reliable
attachment or detachment of the casing 11 due to sliding of the
casing 11. Thereby, it is possible to improve construction.
[0078] Next, a positional relationship between the water supply
pipe 13a and the electrical power supply cord 13b in a state where
the casing 11 is mounted will be described with reference to FIG.
9A and FIG. 9B. FIG. 9A and FIG. 9B are illustration diagrams of a
positional relationship between the water supply pipe 13a and the
electrical power supply cord 13b.
[0079] As illustrated in FIG. 9A, a position of connection of the
water supply pipe 13a to a water supply inlet is arranged below a
position of connection of the electrical power supply cord 13b to a
connector 15 in the open space 20 that is formed by the recess 12
of the casing 11 and an upper surface of the toilet 2a.
[0080] As illustrated in FIG. 9B, a position of connection of the
water supply pipe 13a is positioned below a position of connection
of the electrical power supply cord 13b, so that interference of
the electrical power supply cord 13b with a cord portion is caused
in a case where the water supply pipe 13a is rotated. Even when the
water supply pipe 13a interferes with a cord portion of the
electrical power supply cord 13b, rotation of the water supply pipe
13a is substantially not disturbed due to flexibility of a
cord.
[0081] Thus, in a case where the water supply pipe 13 in the
sanitary washing device 10 according to an embodiment is configured
to be rotatable, it is possible to avoid interference with the
electrical power supply cord 13b even when the water supply pipe
13a is rotated.
[0082] Next, other examples of a rotation restriction part for the
water supply pipe 13a (rotation restriction parts 21a, 21b, 22)
will be described with reference to FIG. 10A and FIG. 10B. FIG. 10A
and FIG. 10B are illustration diagrams of other examples of a
rotation restriction part of the water supply pipe 13a. Herein,
FIG. 10A and FIG. 10B schematically illustrate, in a bottom view,
the open space 20 formed by installing the casing 11 on an upper
surface of the toilet 2a.
[0083] As illustrated in FIG. 10A, rotation restriction parts 21a,
21b for the water supply pipe 13a are provided in the recess 12 of
the casing 11 (case plate 11b). The rotation restriction parts 21a,
21b restrict rotation of the water supply pipe 13a so as to provide
an angle of rotation .beta., so that rotation of the water supply
pipe 13a is restricted so as not to move from an inside to an
outside of the open space 20. Thereby, the water supply pipe 13a is
not exposed to an outside, and further, it is possible to
correspond to a position of the through-hole 2d in the open space
20.
[0084] As illustrated in FIG. 10B, rotation restriction parts 22 of
the water supply pipe 13a are provided in the recess 12 of the
casing 11 (case plate 11b). The rotation restriction parts 22
arrange the water supply pipe 13a at predetermined positions in a
pinpoint manner. Thereby, it is possible to insert the water supply
pipe 13a through the through-hole 2d reliably. Furthermore, the
plurality of rotation restriction parts 22 are provided as
illustrated in the drawings, so that it is possible to correspond
to a position of the through-hole 2d, even when, for example, the
through-hole 2d is provided at a variety of positions depending on
a specification of the toilet 2a (see FIG. 7).
[0085] Next, other examples of a recess of the casing 11, namely,
an open space, will be described with reference to FIG. 11A and
FIG. 11B. FIG. 11A and FIG. 11B are illustration diagrams of other
examples of an open space (open spaces 20a, 20b). Herein, FIG. 11A
and FIG. 11B schematically illustrate a lower surface (bottom
surface) in a state where the casing 11 is installed on an upper
surface of the toilet 2a, that is, the case plate 11b.
[0086] Furthermore, examples as illustrated in FIG. 11A and FIG.
11B are the open spaces 20 that are formed in a spot-facing shape
depending on arrangement of the water supply pipe 13a. As
illustrated in FIG. 11A, an open space 20a (recess 12a) includes a
first space part 121 and a second space part 122. In the first
space part 121, the water supply pipe 13a is rotatably arranged
from a lateral side to a back side of the casing 11. In the second
space part 122, the water supply pipe 13a is arranged toward a back
side of the casing 11 so as to determine a position thereof, for
example, in a substantially pinpoint manner. Herein, in the second
space part 122, the water supply pipe 13a may be arranged rotatably
at a small angle of rotation that is, for example, approximately 10
degrees.
[0087] Furthermore, a type of a water supply pipe may be changed
depending on the toilet 2a or the like, in such a manner that, for
example, the water supply pipe 130a of an elbow type (see FIG. 6B)
is used as a water supply pipe that is arranged in the first space
part 121 and the water supply pipe 13a of a crank type is used as a
water supply pipe that is arranged in the second space part
122.
[0088] As illustrated in FIG. 11B, an open space 20b (recess 12b)
includes a first space part 123 and a second space part 124. In the
first space part 123, the water supply pipe 13a is arranged toward
a lateral side of the casing 11 so as to determine a position
thereof, for example, in a substantially pinpoint manner. In the
second space part 124, a power supply pipe is arranged toward a
back side of the casing 11 so as to determine a position thereof,
for example, in a substantially pinpoint manner. Herein, in the
first space part 123 and the second space part 124, the water
supply pipe 13a may be arranged rotatably at a small angle of
rotation that is, for example, approximately 10 degrees.
[0089] Furthermore, for example, the water supply pipe 130a of an
elbow type (see FIG. 6B) may be used instead of the water supply
pipe 13a of a crank type.
[0090] Thus, the open space 20a, 20b that is dependent on
arrangement of the water supply pipe 13a (or the water supply pipe
130a) is formed, so that it is possible to insert the water supply
pipe 13a through, for example, the through-hole 2d of the toilet 2a
reliably. Furthermore, it is possible to deal therewith, for
example, even in a case where the through-hole 2d is absent in the
toilet 2a (see FIG. 7). That is, it is possible to improve
construction.
[0091] Furthermore, the toilet apparatus 1 according to an
embodiment includes the sanitary washing device 10 as described
above, so that the water supply pipe 13a, the electrical power
supply cord 13b, or the like is arranged between the open space 20
and an upper surface of the toilet 2a in the sanitary washing
device 10, and hence, it is possible to lay the water supply pipe
13a, the electrical power supply cord 13b, or the like in the open
space 20. Thereby, it is possible to improve construction.
[0092] Furthermore, the toilet apparatus 1 according to an
embodiment includes the through-hole 2d, so that it is possible to
insert the water supply pipe 13a, the electrical power supply cord
13b, or the like through the through-hole 2d. Thereby, it is
possible to hide the water supply pipe 13a, the electrical power
supply cord 13b, or the like. Furthermore, the water supply pipe
13a, the electrical power supply cord 13b, or the like is not
exposed to an outside, so that it is possible to further improve a
design.
[0093] According to an aspect of an embodiment, it is possible to
improve a design or construction thereof.
[0094] Configuration (1) is a sanitary washing device, including a
casing, a water supply pipe that is connected to the casing, and a
recess that is arranged on one of left and right peripheral sides
of the casing and forms, on a lower surface of the casing, an open
space capable of laying the water supply pipe.
[0095] According to configuration (1), it is possible to arrange a
water supply pipe in an open space arbitrarily, so that it is
possible to draw such a water supply pipe in an arbitrary direction
in such an open space. Thereby, it is possible to lay a water
supply pipe in an arbitrary direction in an open space, and
further, it is possible to lay such a water supply pipe on a back
surface of a casing without being exposed to a side surface of the
casing, so that it is possible to improve a design thereof. For
example, in a case where a sanitary washing device is installed on
a toilet, it is possible to lay a water supply pipe in a toilet, so
that it is possible to improve a design thereof. Furthermore, a
water supply pipe is also laid readily, so that it is possible to
improve construction thereof.
[0096] Configuration (2) is the sanitary washing device according
to configuration (1), wherein the water supply pipe is connected to
the casing to be rotatable in a surface direction of the lower
surface.
[0097] According to configuration (2), a water supply pipe is
rotated, so that it is possible to lay such a water supply pipe in
an open space. Furthermore, for example, in a case where a sanitary
washing device is installed on a toilet, it is possible to cause a
water supply pipe to correspond to a through-hole that is provided
at an arbitrary position on a toilet in order to execute insertion
thereof. Thereby, it is possible to insert a water supply pipe
through a through-hole readily and reliably. Thereby, an
installation operation is facilitated and it is possible to improve
construction thereof. Furthermore, it is also possible to lay a
water supply pipe outside a casing, so that an installation
operation is facilitated and it is possible to improve construction
thereof, even in a case where there is no through-hole in a
toilet.
[0098] Configuration (3) is the sanitary washing device according
to configuration (1), further including an electrical power source
cord that is connected to the lower surface of the casing, wherein
the electrical power source cord is arranged in the open space.
[0099] According to configuration (3), an electrical power source
cord is arranged in an open space, so that it is possible to lay
such an electrical power source cord arbitrarily in such an open
space and it is also possible to improve construction of such an
electrical power source cord. Furthermore, it is possible to insert
an electrical power source cord through a through-hole. Thereby, it
is possible to hide an electrical power source cord. Furthermore,
an electrical power source cord is not exposed to an outside
thereof, and thereby, it is possible to improve a design
thereof.
[0100] Configuration (4) is the sanitary washing device according
to configuration (3), wherein a connection position of the water
supply pipe is provided below a connection position of the
electrical power source cord.
[0101] According to configuration (4), in a case where a water
supply pipe is configured to be rotatable, it is possible to
prevent interference with an electrical power source cord even in a
case where such a water supply pipe is rotated.
[0102] Configuration (5) is the sanitary washing device according
to configuration (1), wherein the casing includes a rotation
restriction part that restricts forward rotation of the water
supply pipe with respect to the casing in the open space.
[0103] According to configuration (5), for example, an installation
operation is executed in a state where rotation of a water supply
pipe is restricted, so that such an installation operation is
facilitated and it is possible to improve construction thereof.
[0104] Configuration (6) is the sanitary washing device according
to configuration (1), wherein the casing is fixed on a toilet by a
mounting plate provided on an upper surface of the toilet and slid
on an upper surface of the mounting plate in a forward or backward
direction and thereby provided to be attachable to and detachable
from the mounting plate, and the recess has a length in a forward
or backward direction that is equivalent to an amount of sliding of
the casing.
[0105] According to configuration (6), a length of a recess of a
casing in a forward or backward direction is a length that is
equivalent to an amount of sliding to mount a casing, so that it is
possible to arrange such a recess at a predetermined position (for
example, a position where a through-hole is included in an open
space) reliably, due to sliding of a casing. That is, it is
possible to realize reliable attachment or detachment of a casing
due to sliding of a casing. Thereby, it is possible to improve
construction thereof.
[0106] Configuration (7) is the sanitary washing device according
to configuration (1), further including a decorative cover that is
mounted on the casing and covers at least a part of a side surface
of the casing, wherein the decorative cover extends downward in
such a manner that a part that covers the side surface of the
casing covers an open part of the open space.
[0107] According to configuration (7), it is possible to hide an
inside of an open space from an outside thereof. For example, in a
case where a water supply pipe or an electrical power source cord
is arranged in an open space, it is possible to hide it.
Furthermore, a water supply pipe or an electrical power source cord
is not exposed to an outside thereof, so that it is possible to
improve a design thereof.
[0108] Configuration (8) is a toilet apparatus, including a
sanitary washing device; and a toilet with the sanitary washing
device being installed thereon, wherein the sanitary washing device
includes a casing, a water supply pipe that is connected to the
casing, and a recess that is arranged on one of left and right
peripheral sides of the casing and forms, on a lower surface of the
casing, an open space capable of laying the water supply pipe.
[0109] According to configuration (8), a water supply pipe, an
electrical power source cord, or the like is arranged between an
open space and an upper surface of a toilet in a sanitary washing
device, so that it is possible to lay a water supply pipe, an
electrical power source cord, or the like in an open space.
Thereby, it is possible to improve construction thereof.
[0110] Configuration (9) is the toilet apparatus according to
configuration (8), wherein the toilet includes a though-hole where
at least one of the water supply pipe and an electrical power
source cord that is connected to the lower surface of the casing is
inserted therethrough.
[0111] According to configuration (9), it is possible to insert a
water supply pipe or an electrical power source cord through a
through-hole. Thereby, it is possible to hide a water supply pipe
or an electrical power source cord. Furthermore, a water supply
pipe or an electrical power source cord is not exposed to an
outside thereof, so that it is possible to further improve a design
thereof.
[0112] Although the invention has been described with respect to
specific embodiments for a complete and clear disclosure, the
appended claims are not to be thus limited but are to be construed
as embodying all modifications and alternative constructions that
may occur to one skilled in the art that fairly fall within the
basic teaching herein set forth.
